1.If my car gets 26 miles to the gallon and the tank can hold 13.2 gallons of gas, how many miles can I travel?

343.2 miles

Explanation:

To find the miles that you can travel with 13.2 gallons of gas, you can use a rule of three given that you know that the car gets 26 miles to the gallon:

    1 gallon   →   26 miles

13.2 gallons →        x

x=(13.2*26)/1

x= 343.2

According to this, the answer is that you can travel 343.2 miles.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
